Odor gas detection is important in explosives detection, environmental sensing, biometrics, foodstuff and more comfortable life. In this paper, we tried to detect odor chemicals with optical method. We used five kinds of fluorescence dyes, fluorescenin, acridine orange, pyrene, quinine sulfate, and tryptophan. As analyte, we used following four compounds, benezen, vanillin, and NPOE. It is supposed that PET or FRET mechanism will occur between fluorescence dyes and odor compounds, then fluorescence quenching will observed. Indeed, we could detect odor substances using fluorescence dyes by fluorescent quenching. Odor information could be obtained by response patterns across the fluorescence dyes. Moreover, we captured odor shape image and odor spatiotemporal images with cooled CCD camera. Shapes of target which emit odor could be roughly recognized by odor shape image. From the odor spatiotemporal images, two-dimensional odor expanse could be obtained.
